A new suppressor of a lamB signal sequence mutation, prlZ1, maps to 69 minutes on the Escherichia coli chromosome.

Journal of bacteriology - 1 Sept 1994

Wei S Q, Stader J

Abstract excerpt

Reversion analysis has been employed to isolate suppressors that restore export of a unique LamB signal sequence mutant. The mutation results in a substitution of Arg for Met at position 19, which prevents LamB export to the outer membrane and leads to a Dex- phenotype. Unlike other LamB signal sequence mutants utilized for reversion analysis, LamB19R becomes stably associated with the inner membrane in an...
